Allweiler, germany, manufactures three screw pump for managing fluids without lubricating property. Trade named as tritec, the three screw pump has various advantages including high speed, high pressure developments, very low noise and vibrations, and pulsation-free flow. This three screw pump possesses totally different metallurgy for critical parts and are successfully employed for very critical and challenging applications with efficiency, and there by resulting in energy saving and cost reduction. Such critical applications involve predominant injection of liquid fuels for gas turbine, injection of demineralised water for gas turbine for reduction on nox-emission, high pressure fuel firing of any type of liquid fuels, flushing for gas turbine with demineralised water, sea water pumping at high pressure for submarine application, naphtha injection in gas turbines, and high pressure water pumping in reverse nox-emission.
